Hi guys,

I got one of the X5070 Blue end mills from Cutwell tools recently. It is a 6mm dia. cutter with only 6mm flute length, but it has a very slightly reduced shank above the flutes so it can reach to cut 15mm depth, provided you take 6mm passes.

I think this works really well because it is super stiff and gives a great cut quality. However they are expensive!

I was thinking about getting some of the 6mm K2 stub end mills that have 8mm flute length and then having the shank reduced above the flutes so it can reach 20mm (standard they have 6mm dia. cut and 6mm shank so will rub slightly if you cut deeper than the flutes).

Would anybody else be interested in these? I guess the price could be better if I buy more.
